SPECIFICATION.

TO ALL WIIOM IT MAY CONCERN: i v x Bc it known that I, JOSEPH S. DENNIS, of Chicago, in the county of Cook, and State of I llinois,\have invented,` p p a new and useful Improvement in Sad-Irons and I do hereby` declare and make known that the following is a l full, clear, and exact description of the same, reference being had to the accompanying drawings, and the letters l f and figures lruarked thereon, which form part of this specification. 'y y 1. i

y The nature of my said invention consists in soconstructing a sad-iron, that it may be heated as desired ,p introducing and burning inflammable gas or its equivalent therein, `substantially ashereinafter specified.` l 1 p To enable those sk illed in the art to understand how to construct and use my invention, I will proceedto` t describe thesame with particularity, making reference, in so doing, to the aforesaid drawings, `in which- Figure l representsa side elevation of my invention. *A Figure 2 is a longitudinal vertical central section; and Figure 3 is a plan or top view of the same. p l Similar letters of reference in the several figures indicate the same parts-of my invention. t 3 A represents a sad-iron of any suitable configuration, constructed of suitable sheets or plates of metal "or c ast metal, being hollow, as shown, and divided into two chambers, D and E,'by means 4of a horizontal partition` i or its equivalent, as'hereinafter described. B represents a suitable slide or door, whereby access maybe hadto the lower chamber, E, when desired, Yand 'C is theordinary handle of the instrument." P frepresents a flexible lp tube attached to the sad-iron, as shown, the other end thereof being design ed to be suitably secured to` an ordinary p gas-burner or other'device whereby gas may b introduced into said chamber,'D`; representing tubes Lor 3" burners opening downward into the lower chamber, as shown, so that upon igniting` the gas thereat, `a jetof y, l flame is projectedffrom each down upon the bottom of the sad-iron, thereby thoroughly and suriciently heating i p the same; a being aperturesto admit air ixitothe` chamber to supporthcombustion, and F beingia lue toconvey A. p oii .the heated` air, and'eiiect a draught. Instead of having the chamber, D, occupy the entire upperpartof` the i sad-iron, the sadiron may be made of a single chamber, having enclosed withinit, in` the upper `part thereof, an oblong receiver into which the gas may be received, and from which thergas maybe distributed `by the,burners,i`b, as described and shown. Itis designed to have the supply pipe, P, of suiicient'length to allow the' free sliding p, or reciprocating movement of the sad-iron, usually adopted in-- the use of the same. In the forward movement or stroke, the said pipe is extended at length substantially, andin the backwardmovemeut, the` slack infsai'd p pipe is taken up by an elastic cord or band, marked H, which is attachedat two points to theutubepleaving `a p i bow or fold in the tube, but which extends in `length to permit the extension `of said tubewhen desired inthe forward stroke, but which retracts thesame 4as desired when the teuison is removed.. Instead of attachingllthe l y upper end oi" said elastic strap to the tube, it may be attached to any fixed point, as upon thevceiling, themain point being to take up and remove the slack in the tube, produced as aforesaid, `out of the `wayof thetoperaton f If desired, instead of the downward projecting tubes or burners, b, perforations may be made in the,` partition;

i i to allow jets of gas to projectdownwards into the combination chamber, with the samefresults.` 1' .1 i l, l i Having described the construction androperation `of` my invention, I will proceed to specify` whatlI claim and desire to secure by Letters Patenti: l i i t ,p p p p I claim the chambers D and E, with the inlet and exit tubes, connecting pipes or jets b, and orifices 311,1,

constructed and operating substantially as here'indescribed.l p p f J; S. DENNIS.
